At Lars Medicare Private Limited, we specialize in delivering high-quality IV cannulas and related products globally. Understanding the IV cannula parts and their functions is critical for healthcare professionals to ensure safe and effective intravenous therapy. This guide will explore every component of an IV cannula, their purposes, and why choosing the right IV cannula manufacturer matters.
What is an IV Cannula?
An IV cannula is a medical device inserted into a vein to deliver fluids, medications, or nutrients directly into the bloodstream. It provides continuous vascular access and is essential for:
Emergency treatments
Routine fluid therapy
Blood transfusions
Nutritional support
The effectiveness of an IV cannula largely depends on its design and the quality of its IV catheter parts.
Main Parts of an IV Cannula
Understanding the IV cannula parts helps medical professionals ensure safe insertion and effective treatment.
1. Needle / Stylet
Sharp, hollow metal needle used to puncture the vein.
Once the vein is accessed, the needle is withdrawn, leaving the flexible cannula in place.
Available in various sizes to match IV cannula sizes.
2. Cannula Tube
Flexible, biocompatible tube that remains in the vein.
Allows continuous infusion without repeated needle sticks.
3. Hub
Connects the cannula to IV lines, syringes, or extension sets.
Available in various colors corresponding to gauge sizes for easy identification.
4. Flashback Chamber
Transparent chamber indicating successful vein puncture.
Ensures correct placement before withdrawal of the needle.
5. Injection Port / Y-Port
Optional feature for additional drug or fluid administration.
Enhances efficiency during multiple infusions.
6. Wings or Grips
Helps stabilize the device during insertion.
Reduces the risk of dislodgement and improves patient comfort.
Products like Safety IV Cannula and Butterfly IV Catheter incorporate these parts for enhanced safety.
Functions of Each Part
Each component of an IV cannula plays a specific role:
Needle – Accurate vein entry.
Cannula – Continuous access for infusion.
Hub – Secure connection for IV lines.
Flashback Chamber – Confirms correct placement.
Injection Port – Multiple drug administration.
Wings – Stabilization during insertion.
Knowing the functions allows healthcare professionals to minimize complications like infiltration, phlebitis, or vein trauma.
